Heat stroke occurs when the body becomes unable to control its temperature. The body's temperature rises rapidly, the sweating mechanism fails and the body is unable to cool down. Heat stroke can cause death or permanent disability if emergency treatment is not given.
Warning signs of heat stroke vary, but may include:
• an extremely high body temperature (above 103° F)
• red, hot, and dry skin (no sweating)
• rapid, strong pulse
• throbbing headache
What to do for heat stroke:
• Get the victim to a shady area.
• Cool the victim rapidly using whatever methods you can.
• Monitor body temperature and continue cooling efforts until body temperature drops to 101-102°F.
• Do not give the victim alcohol to drink.
• Get medical assistance as soon as possible, call 9-1-1.
• Sometimes a victim's muscles will begin to twitch uncontrollably, if this happens, keep the victim from injuring himself, but do not place any object in the mouth and do not give fluids.
• If there is vomiting, make sure the airway remains open by turning the victim on his or her side.
Heat cramps usually affect people who sweat a lot during strenuous activity. They may also be a symptom of heat exhaustion. Heat cramps are muscle pains or spasms usually in the abdomen, arms or legs. Seek medical attention if the person has heart problems or are on a low sodium diet or if the heat cramps do not subside in one hour. If medical attention is not necessary, stop all activity and sit quietly in a cool place. Drink clear juice or a sports beverage.
Heat exhaustion is the body's response to an excessive loss of the water and salt contained in sweat. Those most prone to heat exhaustion are elderly people, people with high blood pressure, and people working or exercising in a hot environment.
Sunburn should be avoided because it is damaging to the skin. Although the discomfort is usually minor and healing often occurs in about a week, a more severe sunburn may require medical attention.

When treating sunburn:
• Avoid repeated sun exposure
• Apply cold compresses or immerse the sunburned area in cool water
• Apply moisturizing lotion to affected area
